The role of developing countries in climate change mitigation has been and continues to be a contentious issue. Developing countries' emissions are predicted to surpass those of industrialised countries within the first half of this century, but no formal commitments to reduce emissions have been made.

This report, prepared for the Pew Center on Global Climate Change, examines six countries — Brazil, China, India, Mexico, South Africa and Turkey — in the context of climate change mitigation. Ongoing efforts in these countries have helped reduce emissions, though not necessarily in the name of mitigating climate change.

The authors find that overall, over the past three decades, these countries have reduced the growth rate of their emissions by 300 million tonnes. The motivations for such efforts include poverty alleviation, economic development, energy security and local environmental protection. This demonstrates that climate change mitigation can and does occur in the context of development that aims to be sustainable.

This report is comprehensive for the countries studied. It is very accessible and likely to be of interest to anyone engaged in the debate about mitigation in the South.

The report is available in pdf format only. An executive summary is availably online here.

On 9 May 1992, the world’s governments adopted the UN Framework Convention on Climate Change. Five years later, on 11 December 1997, governments took a further step forwards and adopted the landmark Kyoto Protocol.

Building on the framework of the Convention, the Kyoto Protocol broke new ground with its legally-binding constraints on greenhouse gas emissions and its innovative "mechanisms" aimed at cutting the cost of curbing emissions. Today, 186 countries (including the European Community) are Parties to the Convention, more than most any other environmental treaty, and the entry into force of the Kyoto Protocol is expected soon.

This guide, prepared in the tenth anniversary year of the adoption of the Convention, explains in detail the commitments of both the Convention and the Kyoto Protocol, along with the "rulebook" for their implementation.

This is the full text of the Framework Convention, which was adopted at the United Nations Headquarters, New York on 9 May 1992. The convention was open for signature at the Earth Summit in Rio de Janeiro from 4 to 14 June 1992, and thereafter at the UN Headquarters in New York, from 20 June 1992 to 19 June 1993. By that date the Convention had received 166 signatures. The Convention entered into force on 21 March 1994.

Several factors influence the costs of greenhouse gas mitigation. This report illustrates the importance of one such factor — international emissions trading — in reducing the costs of carbon control. The authors argue that an international greenhouse gas emissions trading regime will significantly lower global mitigation costs.

The Third Assessment Report of the IPCC's Working Group 1 builds on past assessments and incorporates new results from the past five years of climate change. It descibes the current state of udnerstanding of the cliamte system, and provides estiamtes of its projected future evolution and their uncertainties.

Many hundreds of scientists from around the world participated in the preparation and review of the report, which states that "there is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities".

The Third Assessment Report of the Intergovernmental Panel on Climate Change, published in 2001, is the most comprehensive and authoritative source of information on climate change. Its conclusions confirm and strengthen those of the previous reports: human-induced climate change is a reality and most of the effects will be negative, but a range of mitigation opportunities is available to address the problem.

The Report finds that most of the earth’s warming over the past 50 years can be attributed to human activities, and that its effects are already being felt. Global temperature is expected to increase by 1.4 to 5.8ºC over the next century, a significant increase on the projections of the 1995 Second Assessment Report. This briefing paper summarises the findings of the Third Assessment Report and the debates underpinning them, and discusses the likely outcomes of the Report.
